Polytetrafluoroethylene (PTFE) is a synthetic fluoropolymer of tetrafluoroethylene, and has numerous applications because it is chemically inert. [citation needed] The commonly known brand name of PTFE-based composition is Teflon by Chemours, [3] a spin-off from DuPont, which originally discovered the compound in 1938. [3]
Dupont registered the Teflon trademark in 1944 and soon began planning for post-war commercial use of the new product. [ 5 ] By 1951 Dupont had developed applications for Teflon in commercial bread and cookie-making; however, the company avoided the market for consumer cookware due to potential problems associated with release of toxic gases if ...
Polytetrafluoroethylene (PTFE), better known by its trade name Teflon, has many desirable properties which make it an attractive material for numerous industries. It has good chemical resistance, a low dielectric constant, low dielectric loss, and a low coefficient of friction, making it ideal for reactor linings, circuit boards, and kitchen utensils, to name a few applications.
Teflon flu, aka polymer fume fever, is a term used to describe people who have gotten sick after being exposed to fumes from Teflon pans, according to the National Capital Poison Center.
PFAS are per- and polyfluoroalkyl substances, highly toxic man-made chemicals used in industrial and consumer products since the 1950s. The chemicals have been added to nonstick cookware, water ...
A recent record number of cases of polymer fume fever, also known as "Teflon flu," are putting a spotlight on one of the most common causes of the condition, the use of nonstick pans. Over 265 ...
In dissecting the cylinder, he found a mass of white solid in a quantity similar to that of the tetrafluoroethylene gas. It was determined that this material was a new-to-the-world polymer . Tests showed the substance was resistant to corrosion from most acids, bases and solvents and had better high temperature stability than any other plastic.
Fluorinated ethylene propylene was invented by DuPont and is sold under the brandname Teflon FEP. Other brandnames are Neoflon FEP from Daikin or Dyneon FEP from Dyneon/3M. FEP is very similar in composition to the fluoropolymers PTFE (polytetrafluoroethylene) and PFA (perfluoroalkoxy polymer resin). FEP and PFA both share PTFE's useful ...
